ERNEST SPENCER, OF AINTREE, ENGLAND.

TIP-WAGON.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed .Tune 9, 1910. Serial No. 566,070.

To all whom it may concern Be it known that I, ERNEST SPENCER, a subject of the King of Great Britain, re siding in Aintree, in the county of Lancaster, in the Kingdom of England, have invented certain new and useful Improvements-in Tip-Wagons, of which the following is a specification.

This invention relates to wagons and has special reference to novel means for mounting the body with reference to the rear truck or carriage in order to provide a type of sliding connection permitting the body to be moved longitudinally with reference to said rear carriage a sufiicient distance to allow the load to be dumped when the center of gravity has been shifted to a given point with reference to the rear axle.

In the accompanying drawings forming a part of this application: Figure 1 is a view of the wagon in side elevation. Fig. 2 is a section through one of the bars supporting the body and through a portion of the rear truck.

Referring to the construction in detail, the body is indicated by 12, and the longitudinal bars constituting the principal portion of the main frame of the body by 10. These bars extend lengthwise of the body near the sides thereof and are supported toward the front by the forward carriage or truck indicated by 15, and at the rear by truck 16. The rear carriage or truck is mounted on wheels 17 and is formed with parallel bars 18 mounted below bars 10 of the body and slidable with reference thereto. These bars are spaced as shown in Fig. 2, and are provided with apertures 20 for the accommodation of the pins 21 of the rollers 22.

The rollers are designed to support the weight of the body with reference to the rear truck, and are mounted in such manner that any excessive strain to which the body may be subjected would not cause binding between the bars of the body portion and the bars 18 of the rear truck, these bars being preferably of wood and having a tendency to produce friction unless properly separated and firmly supported in the manner herein described.

On the underside of bars 10 a metallic plate 25 is mounted, and similar plates 26 and 27 are secured to the inner sides of bars 18, separating these bars from the ends of the rollers. Plate 25 is so mounted with reference to the rollers and with reference to bars 10 and 18 that there will be sufficient play to produce free action between the bars and at the same time will properly support them under heavy loads and unusual strain.

An additional plate 29 may be mounted between plates 26 and 27 and located below rollers 22 and spaced therefrom in order to close the channel-like structure described and prevent the bearings of the rollers from being filled up with foreign substances.

In order that the bars 10 and 18 may be retained at all times in the same position vertically and laterally with reference to each other, stirrups 30 are provided, these stirrups being secured to bars 10 and extending below and about the sides of bars 18.

Stops 19 are provided for limiting the movement of the body with reference to the rear carriage, and catches 31 secure the body and prevent the movement thereof with reference to the rear carriage until it is desired to enect the dumping operation. The connection between bars 10 of the body and the forward carriage is by means of pivoted bars 33, the bars 10 assuming a position at an angle with reference to bars 33 when the wagon is dumped by causing the rearward movement of the front truck.

I claim 1. In a wagon a body, bars extending longitudinally of the lower portion thereof, a forward carriage, a rear carriage and means for slidably connecting the body therewith, including a plurality of bars substantially parallel with each other, rollers journaled between the bars of the carriage, bearing plates separating the rollers from the bars of the carriage and the bars of the body portion, and straps connected with the bars last mentioned, and extending below and trans- Versely of the bars of the carriage, said straps preventing vertical and lateral move ment of the bars of the carriage with reference to the other of said bars.

2. In a wagon, a body portion including a plurality of supporting bars, a forward carriage, a rear carriage, and means for slidably connecting the rear carriage with the bars of the body, said means including spaced parallel bars, plates on the inner side of each of said bars, rollers mounted between said plates and journaled in the latter and in the parallel bars, spaced plates arranged perpendicularly With the parallel signed my name this 28th day of May 1910, bars, forming a box structure in which the in the presence of tWo subscribing Witnesses. rollers are located, and straps connected 1 u T With the bars of the body and extending be- ERNES1 SPLB '5 low the parallel bars and immediately belVitnesses:

neath one of the plates last mentioned. G. C. DYMOND, In Witness whereof, I have hereunto O. BARTLETT.
